Ice sheets respond slowly to changes in climate, because they are so massive that they themselves dominate the climate conditions over and around them. But once they start flowing faster towards the shore…

Antarctic climate science is having a moment – a worrying moment. Three new studies have all concluded that the West Antarctic Ice Sheet has begun to collapse. This collapse will impact humanity for generations…

It is no secret that climate change is transforming the polar regions. Retreating glaciers, melting ice-caps and changing sea ice patterns are frequently reported in both the Arctic and Antarctic, and…

Most people saw the warm dry weather from June to September as a welcome, but freak, occurrence. Because, as anyone who invested in floaty dresses, barbecues or expensive sunglasses in previous years will…

Recently NASA reported that this year’s maximum wintertime extent of Antarctic sea ice was the largest on record, even greater than the previous year’s record. This is understandably at odds with the public’s…

The general thrust of the IPCC’s Fifth Assessment Report - released on Friday – can be summarised as: “there is now more evidence that climate change is occurring”. Antarctica and the Southern Ocean are…

Two papers released last week in the journal Nature Geoscience provide evidence that warming and melt in West Antarctica are occurring at levels that are highly unusual compared to natural variability…
